# Hello, World!

> The first blog post.

I thought I'd use this first post to explain the numbering scheme.

As you might expect, each post has an ID. This post's ID is `22.00.0001`.

Blog posts are [breaking the rules](/documentation/jdex-other-methods) they don't fit in the overall structure.

Imagine if every post had a Johnny.Decimal ID: `22.01`, `22.02`, and so on. My navigation tree would soon get out of control. And I'd run out of numbers quite quickly.

This is a nice example of [why I save the `00` numbers](/documentation/the-standard-zeros). In this case I'm using `22.00`, which is the 'meta' ID for the blog category, as an ID to represent **all blog posts**.

Each post then gets its own supplementary ID, starting from `0001`. (I'm assuming I'll never write more than 10,000 posts.)[^1]

[^1]: Let's say I write a post a day. 365 days/year means I could easily hit 1,000 in a couple of years, but at the same rate I'd need to do that until the year 2050 to get close to 10,000. Unlikely.

## Accessing the posts

The main site has a couple of IDs dedicated to **viewing lists of posts.**

There's [`22.01`](/22.02/) which is an index of _all_ posts but only their titles.

If I add 'tags' to future posts, I might use `22.03` and upwards to show pages that list blog posts with a specific tag.

## I'm just having a bit of fun with this

None of this was really necessary. :-)
